Biotin-PEG2-Picolyl Azide is a versatile biotinylation reagent designed for fast, efficient, and biocompatible labeling. The picolyl azide moiety enhances CuAAC click chemistry with alkyne-containing molecules, while also enabling copper-free SPAAC reactions with DBCO or BCN groups. The PEG8 spacer improves solubility and reduces steric hindrance, making it ideal for bioconjugation, imaging, and affinity assays.
